ST-series T4 turbo
ST-series T4 turbo For months you guys have been wanting S-series units in a T4 chassis and slip covers as well as V-band covers and even the big race cover with comparable wheels to the other 70-76's out there on the market. Well we now offer the ST series turbos which will utilize T4 sizing.
We offer compressor wheels ranging in size from:
70mm - 94lbs/min
74mm
76mm
78mm
80mm - 122lbs/min
The T4 Tangential housings are 3.5" Vband and are 84mm turbines, or 3.30"
The A/R's are:
.80
1.00
1.25
All wheels use the latest in ETT technology.
Compressor Covers are:
V-band outlet cover
Slip outlet cover
Race cover with Slip outlet- only available for the 74-80mm wheels.
The race cover on the 78 and 80 were good for 40hp and 50hp respectively.
ETT offers broader compressor maps and higher pressure ratios for the 8 cylinder guys and also for the high pressure guys like the 2JZ's and 4G63's.
Alot of folks ask what does ETT do as far as HP, well our 70mm unit flowed 95 lbs/min or about 1000hp. Feel free to compare that to other 70mm units.
For you guys looking for smaller ones such as twins, we have something coming so be patient.
Our very own "Tiago" on this board will be running our first ST74 with a T4 housing, should be interesting to say the least
. Stay tuned

Are these BB units or conventional ?
How would one of your 70mm ETT compare to an ITS DBB 70mm turbo, used on an EJ22, 2.35 litre Subaru motor...
I will be looking for an upgrade for the ITS DBB T70 very soon.
Would this be placing a 70mm on par with say a GT42 ? or even close to it ?
sorry for not asking a V8 related question....

Here is a pic of a 74mm T4 unit coated running the V-band cover. Turbo should be good for ~1100+hp.
As for comparison, the turbine wheel used in the ST series units is slightly larger then the S-trim turbine wheel used in the GT42/GTS. Its also one of the new LDP (Low drive pressure) turbine wheels
As for bearings, they are standard journal bearing.

The ETT 70 compressor map flows the same as the 42-74 compressor map, but will peak at a PR of 5.0 vs the GT42's 4.55.
